When < a href=" http://www.selfridges.com/GB/en/cat/ralph-lauren-purple-label/" style="text-decoration: none"><font color="black"><b>Ralph Lauren</b></font></a> founded his eponymous label in 1967, it consisted of a single collection of men’s ties. Today, the brand has become synonymous with preppy American style, and Purple Label demonstrates its dapper side. Spun and washed in one of Italy&#39;s most renowned mills, the cashmere of this fine-knit <b>jumper</b> has had its fibres raised - resulting in superior softness. A turtleneck cut and ribbed trims lend it plenty of timeless sophistication.
